Hello, I’ve got a 1998 Ram 2500 with the v10 and an nv4500. I’m looking to swap a 12 valve in because the v10 has three holes in the block and parts are hard to find for them. I need a diagram for the pcm harness on a 1998 12 valve so I can build one. Also, I’ve only messed with deutsch connectors so I don’t know what crimpers I will need for connectors and pins since these aren’t deutsch. I’ve made plenty of harnesses, however it’s only been deutsch.

Goodluck. Have a early 1998 12 valve had a firewall fire. Have four harnesses all 1998 12 valve and nothing exactly like the one burned. Yes its orginal nothing added or deleted.
